According to the International Energy Agency, the inexorable rise in the world'spopulation and increased individual and collective use of energy will mean twicethe amount of energy is consumed in 2030 as was consumed in 2004. Meeting thisneed will require a huge investment of financial resources in an environment in whichenergy is becoming increasingly scarce and thus more expensive. All this will resultin a foreseeable gradual rise in energy prices and also in greater environmentalproblems.

Spain, with an external energy dependence of about 80%, much higher thanthe European average of 50%, will be more vulnerable to these cost factors, whichwill have a greater effect on its competitiveness. Improving energy efficiency is there-fore crucial both in business and in domestic economy. Producing "negajoules" isundoubtedly the most economical form of energy management.

The potential for energy efficiency improvement is still huge, as are the asso-ciated benefits. Recent reports predict significant job creation in the implementationof more efficient technologies in both production processes and in products andservices. The contribution of these technologies to the reduction of greenhousegas emissions and hence anthropogenic global warming is indisputable.

Improving energy efficiency is undoubtedly an important goal of any respon-sible company in sustainability management. It is also an area of activity where every-one gains from the undoubted economic, social and environmental benefits. It alsorepresents one of the most obvious ways of creating shared value and is veryfavourable ground for innovation.

The Club de Excelencia en Sostenibilidad, guided by its mission of promotingsustainability from the corporate sphere, publishes this catalogue with 44 best prac-tices in energy efficiency, trusting they will contribute to business excellence andthe progress of society.

Promoting a culture focused on responsibility, leading to an innovative way ofthinking about global corporate sustainability is one of the objectives of the Clubde Excelencia en Sostenibilidad which, through this Best Practices Catalogue inEnergy Efficiency, presents 44 experiences carried out by either large companies,SMEs or public administration, sharing a wide range of initiatives ranging from meas-ures in infrastructure to dialogue with stakeholders, passing through eco-designand technological innovation.

Integrating business and sustainability is critical for creating new values thatwill maintain confidence and security in the actions of companies. Achieving com-petitive sustainability is possible because different social agents are involved in adefined and shared policy for the management of environmental resources, ensur-ing the development of a sustainable future, as shown by the 44 experiences pre-sented in this publication.

Endesa, as one of the ten companies in the world, within its sector, most involvedin the fight against climate change and member of the Global Compact LEAD ini-tiative created by the United Nations (UN), which groups the world's top 54 com-panies in terms of sustainability, could not fail to be present on this occasion.

Prologue

7PROLOGUE

At Endesa we understand that sustainability is not a voluntary choice; it is anessential and urgent condition to ensure viability in the medium term. In this respect,the commitment to an active energy efficiency policy is a commitment of Endesato the society in which it operates, through an open proposal for promoting energyefficiency from the side of both supply and demand through new business modelswhich are highly profitable from both a business and social viewpoint.

The welfare of society involves consuming energy more efficiently as a premisefor a sustainable and self-supplying energy environment. In this respect, the overallstrategy of Endesa, from the experience of promoting smart grid development, andthe implementation and dissemination of comprehensive service solutions in energyefficiency that contribute to improving the energy consumption of its clients withoutcompromising the quality standards and competitiveness of its services, places usin a position of leadership in the new energy model that will radically change theway we manage the grid and also our relationship with clients.

At Endesa we are confident that the dissemination of the business practicesin energy efficiency presented here will contribute to the advancement of societyand that these examples adopted by the Spanish business sector, taking advantageof the opportunity offered by new technologies, will help achieve a more responsibleconsumption and promote a new economic model which, while limiting the envi-ronmental impact, ensures the progress of societies and the economic returns ofcompanies by generating new business opportunities and more efficient manage-ment of resources.

RESOURCES, ENSURINGTHE DEVELOPMENT OF A

SUSTAINABLE FUTURE”

Growing concerns about the environmental situation and the effects of climatechange have led countries and international organizations to focus their attentionon sustainability-based development models.

In this context, the United Nations General Assembly proclaimed 2012 the International Year of Sustainable Energy for All, with the firm conviction that itwould be an engine to drive this new model as well as for the achievement of theMillennium Development Goals.

In this respect, the European Commission estimates that a 20% reduction inenergy consumption from the member states would save about 50,000 millionEuros a year, reduce CO2 emissions by 740 million tonnes and create more thantwo million jobs.

In the case of Spain, an investment of 137,391 million euro on the implementa-tion and development of ICT could generate savings of 601,802 million euro forthe period 2011 – 2020, including 47,639 million euro which come from energysavings, as reveals the Spain20.20 report drawn up by Club de Excelencia enSostenibilidad.

For this it is essential for governments and businesses to work together topromote public policies and strategies that encourage the use of cleaner energyand better use of fossil fuels. The role of business is crucial in achieving this goal,either by promoting the access of people to this type of energy or by optimizingtheir internal processes through self-sufficiency with renewable energy or byadopting energy efficiency measures.

Introduction

ENERGY SAVING IN WATER UTILITIES

ABB

115CLIMATE CHANGE

ABB works with large centrifugal pumps tosupply towns with the demand of drinkingwater. These pumps work at 100% capacitybut with oversized engines, so the companyintends to find the balance point that allowssaving and at the same time meeting thewater supply demand, which is achieved byslowing down the engine speed with a fre-quency converter.

Having a pump or fan working at 100% ca-pacity does not mean that there is no scopefor savings; these appliances are often over-sized and with a slight variation of the speedyou can maintain the demand of the systemand save considerably on costs, energy andCO2 emissions.

Thus, with an investment of 150,000 € for theacquisition and installation of each frequencyconverter, the company gains a return amount-ing to 160,000 €/year. In addition, there are en-ergy savings of 1,400,000 kWh/year and areduction in emissions of 757 t CO2/year.

Aena Airports provides 33 electric-powered vehicles and their charging infrastructure at the airports Madrid- Barajas, Barcelona - El Prat, Palma de Mallorca and Lanzarote. To track the distances the vehicles cover,their consumption, battery changes and a number of other parameters to provide reliable data on the suit-ability of implementing electric mobility in the remaining airports, a system for collecting and recording en-ergy and motion parameters is included which is distributed between the cars and the charging points. Theelectric vehicles are used in the same way as their conventional counterparts and are driven by the samestaff.

In the absence of energy verification and battery development data, the result of usage is clearly positive:autonomy, performance and charging times are satisfactory; driving comfort is higher than in cars with ther-mal engine, which leads to their acceptance by drivers. Environmental respect, related particularly to thedisappearance of local NOX and CO2 emissions, is linked to an improvement in the working conditions ofthe airport staff.

GRUPO LECHE PASCUAL

The Sustainable Mobility and Transport Programme is part of the Environmental Sustainability Plan ofthe Grupo Leche Pascual. This is a cross-cutting Plan, integrated in the business strategy and based on theEU 2020 Strategy.

This programme involves mainly the progressive renewal of the distribution and marketing fleet with lesspolluting vehicles; concluding voluntary agreements with public administrations, associations and clients;the promotion of sustainable mobility among employees and the use of new technology.

Specifically, a total of 550 short-haul hybrid vehicles are acquired for the 100% renewal of the commercialnetwork fleet, 25% of diesel lorries are replaced by lorries powered by alternative energy (LPG, natural gas,electric) in the goods delivery fleet and 20% in the logistics and distribution fleet by long-distance EEVs-Enhanced Environmentally-friendly Vehicles, to which a vehicle powered by compressed natural gasis added.

Voluntary agreements are made with the city council of Madrid, Proclima Forum commitment, for the re-placement of 6% of the fleet by less polluting vehicles before 2012, reaching 13%; with the city council ofBarcelona, Agenda 21; with the Confederación de Cascos Históricos de España -COCAHI-1, for the supply

with sustainable transport in the Barrio de las Letras2

in Madrid; and with clients, for the supply with sus-tainable vehicles, such as the agreement with Uni-bail Rodamco.

To promote sustainable mobility among employees(pilot test in the Barajas Delegation) actions aretaken to promote the use of car pooling or publictransport to get to work; reconciliation measures areused and trade routes are allocated by proximity tothe home and the overnight stay of vehicles on thepremises is permitted.

In addition, e-commerce is ventured into throughthe www.clienline.es platform and rout-

ing software is installed to opti-mize mileage and vehicle load.

Through this project a 23% re-duction in emissions and 17%energy savings are achieved.These data are calculated onthe basis of the reduction in fuelconsumption by fleet renewal.

Intangible benefits An improved corporate image, reputation and better relations with au-thorities, clients, consumers, employees, associations, NGOs and otherinterested parties. In addition to an increased visibility due to repercus-sions and coverage in the media.New business opportunities and facilities to carry out the distribution withthe sustainable vehicle fleet in cities.Stronger commitment to social responsibility due to the measures to rec-oncile work and private life and the lower impact on the environment.

Lessons learnedEnvironmental problems can be turned into business opportunities andgreater competitive advantages. Studies can be carried out on new proj-ects of goods distribution in cities based on the distribution models in“clean” European cities. For this purpose it is also important to make theprogram known in the forums in order to exchange experiences withother companies.

Carbon footprint

The Sustainability Plan of LKS Ingeniería aims to implement a mechanism for the control and monitoring ofindicators of the environmental impact arising from the service. Environmental impact has an implicit cost inthe service of the company, so its reduction leads to economic savings and improved service efficiency.

The cost savings, implicit in reducing the impact, comprise the budget for the development of new servicesfor the new green economy, so the plan is coordinated with the Innovation Plan for the development of newbusinesses which provide service in these new markets.

While new businesses are tracked for fundraising, billing and operating account, in the area of environmentalimpact reduction, the economic objective is linked to several factors that are unified under the concept of eco-logical footprint. LKS takes the measure of CO2 emission equivalent to (Kg CO2e) as unit to unify all indicators.

Thus, the Sustainability Plan has two mechanisms: an internal one, for emission reduction, and an external one,for the development of products based on the cost savings generated by the first. Therefore the Plan setstargets for the reduction of Kg CO2/person/year, with the goal of reducing emissions by up to 30% by 2015,and it undertakes to compensate for what has not been reduced.

In terms of energy savings, it launches awareness cam-paigns among its employees in order to reduce con-sumption by 10% in the first year of the Plan (225kWh/person/year) and, thereafter, gradually increase thereduction up to 30% by 2015.

After the first two years of the implementation of thePlan, the company manages to exceed expectations todate with energy savings of 344 kWh/person/year andan emissions reduction of more than 20% kg CO2/per-son/year.

In addition, the new services for the new green econ-omy are showing a significant upward trend. Theturnover of projects with environmental elements, such

as consultancy, building or sustainable certifi-cation, increased from 10% in

2008 to 30% in 2011. Intangible benefits Currently the markets are more demanding, this cross-cutting dynamic al-lows LKS to unify its services and give them a comprehensive response. Fur-thermore, the experience in sustainable services is a key differentiator inthe process of internationalization of the company.It manages to involve the entire organization in the process of generatingnew services and in the innovation of ways to reduce emissions. The teamsinvolved and the rest of the organization are proud to be part of a sociallyand environmentally responsible business project.

Lessons learnedThe addition of the environmental dimension to the aims of the companyrequires a diligent and disciplined commitment to sustainable development.This goes beyond the professional level since it involves a major commit-ment by all employees, but in turn, performing this exercise with the rigourit deserves opens the doors to collective creativity and enthusiasm to tacklechallenges with shared values.

PEPSICO IBERIA

In 2010, PepsiCo published a number of specific global aims to guide its activities until 2015. In the envi-ronmental area, the company undertakes to improve the efficiency of water and electricity use by 20% andof fuel use by 25%.

Within this framework, at its Carregado plant, in Portugal, the company is carrying out a project for theproduction of biogas from the organic load of the wastewater from the treatment plant, which is then usedto heat the reactor and for internal consumption. This initiative will help to achieve the target set for 2015and will serve as a pilot project for the subsequent implementation in other plants of the group.

The Carregado plant in Portugal is one of PepsiCo’s eight production centres on the Iberian Peninsula anda benchmark for PepsiCo in Europe in terms of sustainability. The plant engages in the production of crispsand snack products of the brands Ruffles, Lay's and Cheetos, etc.

Through this project, the factory manages to close the cycle: the wastewater with organic load producedin the process of preparing crisps is reused and biogas is generated to be used again as fuel for frying po-tatoes instead of natural gas.

To carry out this project, it has been necessary to invest in a technology that replaces the aerobic processwith an anaerobic process. The application of anaerobic treatment also aims to achieve a 50% reduction inelectricity consumption in the sewage treatment plant and a 75% reduction in the costs associated with thesludge produced.

However, this new system will involve theproduction of biogas equivalent to 5% ofthe natural gas consumption of the fac-tory. Furthermore, depending on thewastewater temperature, up to 5% of thebiogas production can be used to heatthe reactor. Thus, the industrial unit willconsume 5% less than the amount of nat-ural gas currently consumed.

It is also expected that thereduction in CO2 emissionswill be 32,700 t CO2/year,which would avoid the annualpurchase of carbon creditsamounting to 400,000 €.

“ANNUAL COST SAVINGS OF OVER 120 MILLION € ARE ESTIMATED”

Lessons learnedFor maximum efficiency of the project in the short term, it has beenimportant to ensure the operating temperature of the reactor and in-oculate quality sludge in the starting phase.Biogas production is maximized according to the variety of organicby-products that can be introduced into the treatment process andwhich is supported by technology, with special attention to the limitsof oil, fats and solids in suspension.

Additional informationThis project is part of the Environmental Sustainability policies of Pep-siCo, included in its philosophy of Results with Responsibility.PepsiCo Iberia is considered to be a European benchmark in energyefficiency and reduction of water consumption. So much so that itscrisp and snack plants in Burgos and Portugal have reduced waterconsumption by over 30%, exceeding the overall target set on aglobal level by the company for 2015.

DIRECT USE OF NATURALGAS TO REDUCE ENERGY

CONSUMPTION

RENAULT SPAIN, S.A.

227CLIMATE CHANGE

Lessons learnedWhenever possible we must find the most efficientenergy source and avoid using transformed energies.In our case, instead of burning natural gas in a cen-tralized thermal production and then transporting thisenergy in the form of superheated water and using itin the equipment, the gas is burned directly in theequipment and, being in direct combustion in airstream, even the water vapour enthalpy generated inthe combustion is used.

Additional informationThe direct use of gas is a common technique which iscurrently applied in industry in the installation of newequipment. However, with the current conditions,even the renewal of facilities for energy efficiency rea-sons allows acceptable profitability in many cases.

In this project, two old air-conditioning units supply-ing the cabin with air for the application of primer tovehicles, which used superheated water (SHW) forheat input, are replaced by other more modern onesusing natural gas as energy burned directly in airstream, which leads to a significant improvement inenergy efficiency.

Besides the improvement in energy consumption thatthe direct use of gas offers as regards the losses of acentralized SHW production and its distribution net-work, this project has overcome the need to keep thelarge SHW production boilers of the thermal plant inoperation in the warmer months, thus obtaininghigher energy gains and avoiding maintenance andoperating at such times.

Specifically, the energy savings achieved are9,500,000 kWh/year, the reduction in CO2 emissionsis 1,430 t/year and the cost savings are 390,000 €/year.

SACYR

Sacyr carries out the spatial organization of the square Plaza del Milenio in Valladolid and park Parque dela Ribera, the redesign of the bridge Puente de Isabel La Católica and the construction of undergroundparking for 400 vehicles. It also implements the Millennium Dome as a multipurpose hall.

For this purpose, it takes into account the strictest criteria of constructive sustainability from the outset ofthe project. As a premise, it reuses the metal structure of the hall and the concrete structure of the bridge;mainly locally produced materials are used; gravel from excavation is reused; native species with low waterconsumption and low maintenance are planted; rainwater is used and natural runoff is not altered; biodi-versity is increased by planting trees at the square and the riverbanks and the river are integrated into thecity, creating a space for citizens to meet and interact.

In terms of energy, the energy cost of the materials used in construction is limited, as much of possible ofthe energy needed for the implementation of the project is produced in aclean way and the energy required for use is decreased.

Specifically, we manage to reduce the electricity demand of the undergroundparking by 56% and of the remaining facilities by 51% (square, riverside, dome).The same is true of the treated water, achieving savings of 89.3% in the under-ground parking, 64% at the dome, 99.1% in the dome, and 100% in the irriga-tion of the plot.

Thus, the total energy savings achieved are 17,319 kWh/year and the reductionin CO2 emissions is 9.69 t/year.

Today, the Plaza del Milenio project has the following distinctions in sustainability:

Lessons learnedThe initial energy audit should be as comprehen-sive as possible in order to carry out the whole pro-curement and operating process with the maximumpossible guarantees. It is important that all activities are carried out incoordination with representatives of all depart-ments involved: planning, maintenance, parks andgardens, etc.

“COST AND ENERGYSAVINGS UP TO 40%ARE EXPECTED TOBE REFLECTED INELECTRICITY BILLS”

Street lighting in Alcorcón was heterogeneous, areas withold and inefficient lighting coexisted with other more re-cently remodelled areas.

The proposed action consists of three phases: 1. Carryingout an energy audit to identify all necessary investments2. Put out the implementation and operation of the light-ing to tender for 10 years to allow amortization 3. Runningthe project and operating the lighting.

For this process, the involvement of the following agentsis considered appropriate: the City Council, which obtainsthe short-term implementation of investments and whichwill benefit from the resulting savings in energy bills; theIDAE, which provides its expertise and finances the invest-ment and the energy service company, which carries outthe investments and will operate the lighting for the next10 years.

The actions taken include measures for replacing oldlights with other more efficient ones, reducing the bright-ness to meet the requirements of the new regulations onenergy efficiency, remote management of the system, etc.

Since its launch, the project has only been running for oneyear of the 10 years planned, but cost and energy savingsup to 40% are expected to be reflected in electricity bills.

BOLLULLOS DE LA MITACIÓN CITY COUNCIL

The project consists of replacing the street lighting system of the municipality of Bollullos de la Mitación by moreefficient technologies that achieve major reductions in electricity consumption, with no need for investments bythe City Council, so that these savings finance the necessary investment.

Enel Sole and Endesa carry out the replacement project dealing with the management of the supply invoices andadapt them to the lowest bid, and they manage the maintenance of municipal lighting during a 10-year concession.

The benefits which the municipality obtains are various. The most obvious one is that its lighting is renewedwithout having to invest anything or get funding. Another of the most striking benefits is the cost saving since a

lower monthly payment than that existing before the concession is guaran-teed and this payment is fixed, thus, avoiding surprises and enabling it toplan the service budget easily.

There is also a substantial reduction in the effort and resources required tomanage the service and the various supply bills, one for each electrical panelof the installation. Finally, light pollution is reduced and the energy efficiencyof the City Council is increased.

Initial goals are fully achieved. Thus, electric bill savings are 43%, energy sav-ings are 540,000 kWh/year and the reduction in CO2 emissions is 146 t/year.

Currently, Enel Sole and Endesa apply the same model in the municipalitiesof Castro del Rio and Muro de Alcoy; they are the companies with the mostESE projects in Efficient Street Lighting in Spain.

“THE RENEWALOF LIGHTING IS

ACHIEVEDWITHOUT THENECESSITY TO

Intangible benefits• Improvement of the environment for citizens due to the reduction of pollutant emissions, reduced

diffuse and intrusive light, increased security, increased attractiveness of the city and improvedlevel of service and user satisfaction.

• Opportunity for the municipality to be a leader in innovation and a test centre for outdoor lightingsystem technologies, since Endesa continues to implement a number of improvements designedto evaluate and verify certain technology solutions in public lighting installations. Specifically, theyare trying remote management solutions for light sources, which are monitored from the SmartGrid Service Centre; furthermore they are making tests regarding ornamental lighting adjustments.

• Two-way communication with the public: the service includes a public service channel through thetwitter profile, @APBollullos, by which citizens can inform about any service incidents, make sug-gestions, queries, etc. It is also used as a platform to provide information on energy efficiencymeasures in general and on the project in Bollullos, in particular.

• Promotion of new sectors such as the production of efficient lighting, energy audit companies, etc.• Job stability linked to long-term concessions and support at a local and rural level for the employees

of the maintenance companies.

Lessons learned• Information on the installations of the municipalities is outdated. It is necessary to perform a

thorough quality audit prior to the projects.• The projects can be repeated in many municipalities so it is important to spread and promote

the advantages of this model.

SABADELL CITY COUNCIL

In accordance with the sustainability goals set forward by theLocal Agenda 21+10, the municipal strategy for the mitigation ofClimate Change 2008-2012 and the Local Energy Office in the pe-riod 2009-2012 adopt measures for energy saving in municipal fa-cilities and public spaces (lighting, fountains, etc.).

In addition to reductions in energy consumption and greenhousegas emissions, the taken measures allow significant savings (1 mil-lion Euros per year) in a macroeconomic context characterized bythe decreased revenues of the municipalities. These measures in-clude optimizing the schedule at which street lighting and foun-tains are turned on and off, the installation of LED optics in 100%of traffic lights and the remote radio management of 32 lights.

With regard to the new contract between the City Council ofSabadell and the Energy Service Company for street lighting, ineffect for the 2013-2022 period, the contractor must undertake asignificant amount of energy saving investments which will be fi-nanced by the savings themselves.

Specifically, the project reduces the annual energy bill over thisperiod by 30% on average, equivalent to 600,000 € a year. Invest-ments involve, among others, the replacement of all existinglights with new LED lighting (8,500 units), and the increase of thenumber of panels with remote management or remote readingduring 2012 and 2013.

All the measures are developed progressively; those already im-plemented produce annual savings of 834,793 €, this figure is ex-pected to rise to 1,694,105 €. Meanwhile, the annual energysavings achieved today are 6,489,148 kWh and these are ex-

pected to increase to 11,169,148 kWh. Finally, the annual reduc-tion in emissions stands at 1,713,974 kg CO2

and is estimated to increase to2,560,974 kg CO2.

Intangible benefitsAwareness and training of citizens and municipal staff in good energyhabits. Change of the traditional idea that ecology and sustainabilityare a burden on the economy by showing that, on the contrary, theypromote cost savings and innovation.

Lessons learnedIn a difficult economic context for public authorities such as the present,it has been shown that investment can be maintained as long as it fo-cuses on reducing long-term expenditures. That is, short-term spendingis offset by long-term savings. In addition, these investments in energyefficiency enable the prediction and prevention of negative conse-quences for the municipal budget as regards the expected future in-crease in energy prices.

SOTO DEL REAL CITY COUNCIL


The municipality of Soto del Real allocated 242,000 € to street lighting power supply and 196,000 € to itsmaintenance which amounted to a total of 438,000 € a year.

For improved efficiency in outdoor lighting, the City Council put it out to tender specifying that the contractormust make an investment in the renewal of lighting installations and their adaptation to the regulations.

Thus, the selected project proposes a number of energy efficiency improvement measures which lead toenergy consumption savings of 80%, thanks to which the investment of 2,032,148 € made by the energyservice company is financed and the city council achieves a reduction of 47,000 € (10.7%) in the annual feeit has to pay.

The measures taken were mainly the replacement of the 3,277 lights with LED technology; the improvementof the command centres and distribution lines; point-to-point regulation; the addition of a double level thatreduces power by 50% at 1:00 am; the installation of a consumption control system (EMMOS) and an instal-lation management and control system for inventories (ONVIA Lighting), among other measures.

Thus, the municipality meets the initial aims of 1,577,892 kWh/year in energy savings and 1,024 t/year inCO2 emission reduction.

Intangible benefitsWith the new lighting system, in addition to the significant savings of 80% concerning the energypreviously consumed, a crucial step has been taken for the implementation of energy servicecompanies in Spain, proving the feasibility of the new procurement model of public-privatepartnerships in public administration and the introduction of LED lighting.From the citizens’ point of view, the quality of lighting has significantly improved, improvingthe uniformity and chromatic reproduction and furthermore, light pollution has almost beeneliminated completely.

Lessons learnedWe have verified the feasibility of this new business model thanks to the positive results that arebeing achieved. Thanks to the knowledge and experience of energy service companies, com-bined with the financing of investments, public auhtorities can implement projects that signifi-cantly improve energy efficiency and that help meeting national targets for reduction in demandand improvement in energy efficiency. ESCOs undoubtedly play an important role in this field.The Soto del Real project, launched by the IDAE and Spanish Lighting Committee, has been asuccess and serves as model for many other municipalities. Even the Massachusetts Institute ofTechnology is conducting a research project together with the company Ferroser, in collabora-tion with the Soto del Real City Council.

LUMÍNICA AMBIENTAL

Lumínica Ambiental conducts a lighting audit in the municipalities of Pulpí and Segura de la Sierra as partof a pilot project carried out by the municipalities adhering to the Covenant of Mayors for Climate Changein Andalusia.

The light and energy audit has two aims. On the one hand, to specifically define the corrective measuresnecessary to adapt the installations to the required regulations and investment. This entails significant costsavings in the management of this public service and considerable environmental improvement by reducinglight pollution and greenhouse gas emissions. On the other hand, it offers a thorough technical knowledgeof the installation in order to ensure the viability of the service tender through an Energy Service Company(ESCO).

Thus, Lumínica Ambiental works on a total of 1,297 light sources and 18 control centres. The tasks theyperform in the lighting audit are:

- Detailed inventory of the installations: collection and processing of the initial information, which is ex-tended and updated to the actual situation. For this purpose, extensive fieldwork is carried out.

- Measurement of nocturnal light levels, using the mobile unit with three geo-referenced light meter probesand data management software to generate light data and maps and include them in a GIS (GeographicInformation System) and compare different areas of lighting or the same area at different times, whichwill enable the monitoring of the operation and the performance of actions.

- Assessment of the current situation, comparing the item data and measurements obtained with currentlegislation. Actions are identified according to their priority for adaptation to the regulations.

- Technical and economic analysis of the solutions, supplying the necessary investment data, along withthe expected savings and environmental improvements in relation to the reduction of light pollution.

Thanks to the improvements proposed by these audits, there will be estimated annual cost savings of50,371 €, energy savings of 457,918 kWh/year and CO2 emission reductions of 212.12 t/year.

Lessons learnedThis project allows us to corroborate that the light and energyaudit is a fundamental prerequisite for the subsequent prepa-ration of the specifications for the procurement of the streetlighting service in the form of energy service, and for this totake place under conditions that ensure correct lighting serv-ice, proper functioning of lighting and maximum savings forthe municipalities and fair economic conditions for the bid-ding companies.The appropriate balance occurs only if the audit is done underindependent criteria regarding external components andbearing in mind sustainable energy criteria to provide ade-quate lighting while ensuring the safety of users, reducingconsumption by using the maximum energy efficiency and re-specting the environmental quality of residential areas and re-ducing light pollution.

To achieve 20% savings of kWh/m2 electricity by 2020 and, therefore, a 20% reduction of CO2 emissions,Alcampo has launched an action plan ranging from the introduction of more efficient technical innovationsto the improvement of management systems and the staff involvement.

Specifically, technical improvements such as LED illumination, efficient roof top air-conditioning with refrig-erated recovery, closed refrigeration furniture, speed shifters, motion detectors, etc. are installed.

However the company acknowledges that the success of a 13% reduction in energy in 3 years is the resultof the work and involvement of maintenance crews and employees in general, to whom the following activ-ities were aimed:

1. Implementation of an e-learning training course about the importance of saving energy from an envi-ronmental and economic point of view, given to 70% of the workforce.

2. Internal communication campaign using the following tools: posters with general good habits, specificposters of the maintenance sector, identification stickers on light switches, intranet and internal newslet-ter.

3. Creation of an energy efficiency label to know the consumption in energy units (kWh) of each large su-permarket; this information is part of a new indicator that is analysed every six months and which formspart of the system of aims.

4. Implementation of maintenance synergies: in each large supermarket, there is a maintenance team thathas been directly involved, holding videoconferences twice a year for benchmarking, sharing the bestmethods and troubleshooting among the maintenance managers themselves.

5. Implementation of maintenance software to integrate all the know-how and share it online.

Finally, the result of all the actions is an energy saving of 35,300 MWh and an emission reduction of8,700 t CO2eq.

Intangible benefits The external survey results reveal that 91% of our cus-tomers think that Alcampo is committed to the envi-ronment.

Lessons learnedBeyond technology and large investments, we be-lieve that informed and trained people can achievegreat savings and have a very positive impact on theenvironment. It is also a commitment that transfersthe borders of the company; the people who havebeen passionately involved in the project are highlycommitted citizens.

INDUSTRIA DE TURBO PROPULSORES, S.A.

ITP considers the energy efficiency of the whole compressed air system of the plant and defines the savingstarget pursuing a dual optimization: firstly, reducing the electricity consumption which is necessary to gen-erate compressed air, and secondly, using the heat energy generated in the compressor so that residualheat can be converted into useful heat.

For this purpose, the whole installation is analysed and actions are taken to improve various aspects:

- Compressor operation cycles are optimized, programming stops at night time and on weekends.- Air leak detection tests are launched throughout the entire network and awareness campaigns on the

proper use of compressed air are made, thus securing the involvement of staff in this improvement.- Operating conditions are optimized, adjusting pressure to the needs of each job, depending on the task

to be performed.- A system is designed to recover heat from the compressor cooling system and use it for heating the build-

ings and warehouses near the compressor room. Previously, air quality controls are performed to ensurethat the improvement takes place in optimal conditions for the well-being of workers and facilities.

By this method, savings of 45,500 € a year are achieved, 47% more than the initially stated goal and thismeans 50% of all cost savings achieved in the plant in 2011 by improving energy efficiency.

There are also savings from reducing preventive and corrective maintenance achieved by the optimizationand reduction in operating hours of the compressors. Furthermore, by achieving a more linear electricityconsumption graph, the financial penalties for exceeding the maximum contracted power consumption arereduced.

As regards energy saving, a reduction of 926,005 kWh is achieved, divided into 346,106 kWh of electricityand 579,899 kWh of heat. This means 5.1% of the electricity consumption and 8.34% of the natural gas con-sumption of the plant in 2010. And as for the reduction of emissions, a reduction of 244.2 t CO2 is achieved,which corresponds to 6.2% of the emissions generated in 2010.

Intangible benefits Awareness campaigns and staff participation have promoted the launchof new suggestions. The training on energy efficiency was highly ap-preciated by the participants, who suggested extending it to more em-ployees, and as a result, work groups were created to identify actionsto improve energy efficiency in different areas of the plant. These ac-tions were assessed and some of them have been included in the newenvironmental management programme.

Lessons learnedImproved energy efficiency is higher if measures are defined focusingon different aspects: equipment and facilities, operation, saving, recov-ery, user actions, etc.If workers are involved in the definition of improvements, their involve-ment in the implementation, maintenance and defence thereof isstronger. It also helps if the improvements carried out in the companycan be applied at a personal and/or household level.Many savings and efficiency concepts can be applied not only to dif-ferent forms of energy but also to overall resource consumption. In-vesting in staff training and awareness leads to an improvement in otherareas of the organization.

“STAFF AWARENESS INENERGY SAVING ISTRANSFERRED TO THEDOMESTIC SPHERE”

In order to reduce energy consumption in the SENER office buildings, the company launches a plan ofgradual modernization of electrical equipment for lighting, with elements of higher performance and effi-ciency.

To optimize this action, timers and presence detectors are placed in corridors and toilets. In addition, equip-ment is acquired for engineering and service processes with energy saving criteria, incorporating reducedpower systems during periods of inactivity and using black screensavers with an action time of no morethan five minutes.

At the same time, environmental education and awareness campaigns are conducted among employeeswith key messages, such as: turn off computers, lighting, air conditioning, screens, printers and plotterswhen they are not necessary and overnight, use screen energy savers, etc..

In the new infrastructure, as in the case of Tres Cantos and Barcelona, adjustable lighting is installed whichturns on and off depending on exterior lighting, thus, reducing electricity consumption, emissions and costs.

Due to the recent implementation of the project, there does not exist any quantifiable data, so far.

GESTAMP

The weight of cars has a direct relationship with fuel consumption and emissions to the atmosphere. A 10%reduction in the weight of a 1,500 kg vehicle is estimated to lead to a reduction in emissions of 10-20 g CO2/km.It is therefore very important for the parts of bodywork to be as light as possible, provided they meet the tech-nical requirements and maintain a competitive cost position.

In this particular case, Gestamp has made a component of the front suspension, the lower control arm,which equips a platform shared by several utility models, lighter and less expensive than other solutions of-fered in cast or forged aluminium.

By the use of advanced high resistance steels, combined with the latest developments in simulation tools,a lighter, lower weight and cost solution is sought to help clients achieve their emission reduction targets.

The development takes place in cooperation with one of the main clients of the company, focused on oneof its platforms with the greatest production volume.

So, after agreeing on the requirements that the solution must meet in terms of fixing points and attachments,maximum volumes, resistance, stiffness, fatigue life and impact resistance, an optimized solution is soughtby using simulation tools.

The first results lead to a mono-shell solution with strong potential for reducing weight and cost, based onthe use of the latest generation steels. Being very high strength steels, simulation tools are used to verifythe feasibility of the initial geometry and ensure that it falls within the parameters set forth by the manufac-

turing technologies that are to be used (bodyworkstamping, conventional welding). This leads to a re-peated optimization process which concludes with asolution slightly below the initial objectives but verysatisfactory.

The next step is to validate the solution through com-prehensive testing of prototypes and verification ofcompliance with the requirements, allowing the re-lease of the design and the start of mass production.

Although the aim of this project is not to save energyunits during the production process of the part, it fo-cuses on reducing the weight of the latter which has adirect impact on vehicle fuel dependence and the re-duction of emissions during the lifetime of the product.

In this respect, a 12% reduction is achieved inthe weight of the part compared to the alu-minium solution and a reduction of 3,000 t ofCO2, on the assumption that a vehicle coversan average of 15,000 km per year, saving 15gof CO2 per kilometre and per each 120 kgweight reduction.

Intangible benefitsInternal image of commitment to the environment.

Lessons learnedRenewable energies have their place in many areas ofthe industry. This first project has led to further feasibilitystudies such as cogeneration.

In 2007, a study was conducted on the possi-bilities of implementing renewable energy inthe Grupo Antolin; thus, identifying the oppor-tunity to locate a solar energy park in the carpark of the main building, as it disposes of thesufficient surface for this purpose.

Moreover, the project is designed with a dualpurpose. On the one hand, to generate renew-able energy and, on the other, to provide a rooffor employees’ vehicles to be better protected.

Thus, different types of panels are studied fi-nally opting for the BP Solar, which has a higherprice but also a higher performance. An agree-ment is made with a local company for their in-stallation.

Due to this project, the Grupo Antolinachieved a reduction in energy consumption of608,827 kWh/year and a reduction in CO2 emis-sions of 700 t/year. The recovery of investmentfor this project will be achieved in nine years.

GRUPO EROSKI


INNOVATION

Eroski aims to create the first Zero Store model, validated in real environment, which identifies the eco-efficient measures that in combination reduce the impact on the environment, i.e. reduction in energy de-mand by application of additional savings measures to the usual type of construction, the area of applicationbeing the main installations (lighting, industrial refrigeration and air-conditioning) and the facade of thebuilding, taking into account the interaction between different systems and equipments.

In this "lab store" eco-efficient solutions are integrated and combined, providing it with a tool for the sim-ulation and validation of the implemented measures and a system for the control and monitoring of savingsper unit and for all solutions. Subsequently, eco-generation measures were integrated, the possible exten-sion of these to the entire sales network being under consideration.

At the Zero Store, measures to reduce the impact of the centre on the environment, both through a re-duction in energy consumption and through the implementation of sustainable construction measures, aretested and identified, ensuring that the implementation of these new developments is kept within sustain-able economic parameters.

In accordance with the aforementioned information, once the investment has been recovered, cost savingsof 50,000 €/year, energy savings of 520,000 kWh/year and a reduction in CO2 emissions of 195 t/year areexpected.

Through this initiative, the Grupo Eroski has become the first food retailer to integrate in a "lab store" eco-efficient technologies and construction which have never been used together before.

“AT THIS “LAB STORE”ECO-EFFICIENTSOLUTIONS AREINTEGRATEDAND COMBINED”

Intangible benefitsBesides achieving an unprecedented store due to the associatedenergy results, it has been possible to sensitize all the stakehold-ers involved, specifically by developing a training plan for thestore team and by launching a customer education and aware-ness plan.

Lessons learnedThe development of this store has allowed Eroski to verify thatall phases of a project of this kind have a direct impact on thefinal result, the energy performance of the building and its use.It has been possible to considerably improve the sustainabilityof the "lab store" by the preconception of the model, the defi-nition of the project or simply the choice of the location of thebuilding.Nevertheless, the results obtained encourage to continue work-ing to improve the stores so that the impact of the activitythrough 100% sustainable stores can be mitigated.

METRO BILBAO, S.A.

Trains accelerate and brake regularly. Each time a train accelerates, it stores kinetic energy which is releasedat the braking process. The kinetic energy of the train is converted into electrical energy by the traction en-gines and the associated converter.

Thus, a braking train provides energy to the overhead power cable if another train is accelerating nearby atthe same time. If this simultaneous timing condition is not met, the energy generated by the braking processwould burn in the resistors located in the train for that purpose.

The development of Metro Bilbao is to create reversible substations which are capable of returning the en-ergy that was previously burned in resistors, to the network since before the launch of this project the over-head power cable consisted of rectifier bridges with non-reversible energy flow.

For this purpose, a unit is installed consisting of a converter connected between the overhead power cableand the secondary existing traction transformer, at the same time with the substation rectifier, to enable thereturn of surplus power from the overhead power cable.

This design enables to maintain always the existing infrastructure at the substation (transformer, rectifier,switchgear and electrical protection). The basic equipment consists of:

- AC/DC inverter with elevator copper, which permits power to be returned to the network, reusing existingsubstation transformers

- Circuit breaker for the protection and insulation of substation equipment- Resistors for bus discharge and protection against overvoltage

The final results of this project are not yet quantifiable, but, so far, meet the expectations that were set forward.

INNOVATION

The new MRW Central Services building, located in L'Hospitalet de Llobregat in Barcelona, is designedand built under the criteria of paying respect to the environment with the aim of minimizing the ecologicalfootprint of the company.

It is characterized by its large savings in the consumption of resources and the efficient management ofthe generated waste, while providing at the same time a high degree of user comfort. Specifically, energyconsumption is reduced by 50% and water consumption by 40%.

This is possible thanks to the incorporation of solar panels forwater heating, together with the high efficiency of its lightingsystem. It also has a double facade made up of strips that areoriented automatically by light sensors optimizing the use ofnatural light, while the intensity of artificial light required is reg-ulated inside. This system, along with its plant-covered roof im-proves thermal insulation. Similarly, the inductionair-conditioning system (air-water system) generates significantsavings in energy costs

It is worth mentioning that, in order to promote sustainable mo-bility, the location of the building is chosen strategically to alloweasy access by public transport and a parking space is reservedin the car park for recharging electric vehicles and for parkingbicycles.

Thus, this "smart building" becomes a Class A building, accord-ing to the criteria of the Institute for Energy Diversification and

Saving - IDEA, and the first building in Spain to obtain, in the design phase, the Breeam certification withexcellent rating.

“INVESTMENT INSUSTAINABLE ANDENERGY EFFICIENTMATERIALS CAN BEVERY PROFITABLE”

Firstly, the partitions are made to define the space whichshall serve as laboratory in which the Thermic-Wall systemare installed and then the plumbing and electricity instal-lations are carried out to provide the laboratory with thesupplies needed to carry out the tests.

The laboratory work has nothing to do with the work car-ried out in the rest of the building, so sufficient thermaland acoustic insulation is required. On one hand, the pro-duction work carried out in the building produces, at peaktimes, high noise levels which can disturb the work per-formed in the laboratory. On the other hand, the temper-ature and humidity conditions within the laboratory mustbe controlled and shall not be affected by the conditionsof the building, neither in winter nor in summer.

The thermal insulation achieved with the Thermic-Wallsystem results in a saving of the energy used for the air-conditioning of the laboratory, primarily in the coldermonths. Furthermore, it minimizes heat loss, which is verysignificant due to the gradient temperature between theinside and the outside of the laboratory.

Specifically, the partitioning system used for the partitionsallows savings of approximately 40% of the costs involvedin using other materials such as ceramic brick or plaster-board panels, representing savings of 2,400 €/year.

VODAFONE SPAIN, S.A.U.

As in most business activities, the development and provision of telecommunications services involves energyconsumption both for the operation of the network and for store and office activities.

For the continuous improvement of energy efficiency of these activities and the reduction of the associatedenvironmental impact, Vodafone Spain has launched several Energy Efficiency Plans.

In the first of these (2003-2006), actions related to refrigeration systems in the network were implemented, re-sulting in the saving of 3% in energy consumption and 3% in CO2 emissions, i.e. 13,059.1 MWh and 4,637 t ofCO2, respectively.

Later, in 2006, it launched a new Energy Efficiency Plan which includes much more ambitious improvementgoals, including major investments in more efficient technologies.

All proceedings included in this Plan are intended to increase energy efficiency in the Base Stations and Switch-ing Centres, where the measures described below are gradually being implemented:

At Base Stations:

- Installation of heat removal systems at stations with split A/C equipmentthat does not have free-cooling

- Installation of more efficient A/C equipment- Raising of the set-point temperature of stations- Installing or replacing with more efficient equipment in 3G stations- Sharing agreements with other operators

At Switching Centres:

- Installation of refrigeration systems with free-cooling- Turning off unoccupied areas- Removal of obstacles with raised floor- Closing of some centres

Despite the increased activity of Vodafone Spain in recent years, thesemeasures have ensured that power consumption does not increase in pro-portion to the development of the activity.

Specifically, the goal of reducing power consumption by 8% has been ex-ceeded and a 12.8% saving on expected consumption has been achieved.Since the launch of the first Energy Efficiency Plan on the Network, a total

of 141,855 MWh have been saved. Energy reduction through networkelement has been 15.6% since 2006.

The same is true of the reduction of CO2 emissions, thegoal of saving 8% has been exceeded and a saving of11.8% has been achieved, with a 87.6% reduction in CO2

emissions with regard to traffic (the target set was 35%).Reduction of CO2 emissions through network elementwas 29.8%.

Currently, it can be considered that Vodafone Spain hasone of the most efficient networks in Europe.

AQUALOGY AQUA AMBIENTE SERVICIOS INTEGRALES, S.A.

In order to reduce electric energy consumption andgreenhouse gas emissions, several energy audits are con-ducted in all water cycle facilities of Aqualogy all over thecountry; these were distributed as follows:

- 2009: 74 audits reviewed- 2010: 125 audits reviewed- 2011: 129 audits reviewed

The result of the audits leads to the audit reports, whichreflect the potential savings that could be made if all theimprovements detected were implemented along withthe proposed corrective actions to be taken to achievethis goal. This includes actions to improve the perform-ance of existing equipment, adjustment of the contractedelectricity rate and optimization of the operating systemof facilities.

In addition, the analysis and improvement proposals putparticular emphasis on the promotion of new renewableenergy sources: solar and hydro, basically.

They also include an economic study on the recovery ofthe investment required for the implementation of correc-tive actions and the monitoring of the level of executionand capture of savings of the proposals identified.

Specifically, the calculation of cost savingsachievable in the long term through theimplementation of all proposed im-provements is 4,634,291€/year. Thecost savings percentage achievedtoday is 25.6%, i.e. 1,806,723 €/year.

Similarly, the calculation of energy sav-ings is 25,527,128 kWh/year. The per-centage of savings achieved today is35.4%, i.e. 7,199,233 kWh/year. And thereduction in CO2 emissions is 1,943 t.

Intangible benefitsThe fact of conducting audits to improve energy efficiency isin itself a commitment to the environment and to the popula-tion in general. When these audits result in reports with spe-cific data and goals, the commitment can be quantified and,therefore, it is more feasible to carry it out. This adds value tothe corporate responsibility of Agbar and to its environmentalcare image.

Lessons learnedProposals for improvement in these facilities can be summedup as: 1. Study of the most appropriate rate and benefits ob-tained, 2. Analysis of the operating system, with improvementalternatives and 3. Proposals for the performance adjustmentor replacement of equipment.

SECTOR MANUFACTURING,ELECTRICAL APPLIANCES

The heating of factory buildings with a height of more thansix metres worked by supply air systems, previously heatedby a water to air heat exchanger. This implied a higher tem-perature at roof level than at floor level and undesirable con-vection currents for workers.

The radiant tube system emits infrared radiation that gen-erates heat when it is absorbed by a solid body such as per-sons, the floor or the facilities. There is virtually no energyloss because the air can be considered a medium which istransparent to radiation. Its installation is simple as it justneeds to be hung from the ceiling with chains and connectedto the natural gas outlet.

Thanks to this system, significant reductions in natural gasconsumption and CO2 emissions are achieved as well as immediate thermal comfort at work-places andgreater comfort at lower temperatures. Furthermore, it prevents air currents and the airborne dust theycause, heat loss through the ceiling by concentrating the heat at ground level and it is not necessary to turnon the pipes hours before the working day begins because heat is almost immediate.

That is how BSH Electrodomésticos España achieves a 60% reduction in heating consumption with regardsto its previous situation, which amounts to a savings of 4,000,000 kWh/year, prevents the emission of7,344,000 kg of CO2 by reducing the consumption of natural gas and obtains cost savings of 120,000 €/year.

Lessons learnedThe installation of this heating system has allowed thecompany to optimize the resources aimed to thecomfort of persons and also consider eliminating thesome natural gas boiler which was only needed as re-inforcement in the winter season, making its facilitiesmuch more efficient.It is also a very suitable system for factory buildingswhere the ceilings are high and surfaces with differentuses coexist. Because heat can be directed effectively,only the areas occupied by people are heated.Therefore, this action has spread to other factories ofthe company in Santander, La Cartuja - Saragossa andEsquíroz - Pamplona, generating savings in all ofthem of around 40% compared to the previous situa-tion.

The usage phase of buildings is responsible for 84% ofthe energy consumed during the life cycle thereof, so thatthe construction of low demand housing is an urgent needfor the current society.

In Spain, the number of buildings is about ten millionbuildings, of which nearly nine and a half million are resi-dential. About 60% of these homes were built before1980, prior to the appearance of the set of technical stan-dards governing the quality of buildings and, more specif-ically, the first rules to regulate the energy efficiency ofbuildings.

Investment in insulation is the energy-saving measurewhere the best cost-benefit ratio is obtained. Insulating abuilding produces from the first day of operation a reduc-tion in consumption which is accumulated over the life-time of the insulated element.

The facade insulation system, THERMUR, developed byCEMEX, is the best thermal inertia, achieving energy sav-ings of up to 35%. It also gives the facade high durability,water impermeability and water vapour permeability andprovides high acoustic insulation, resulting in greater com-fort and savings.

This is a multilayer building system on the basis of EPS ex-panded polystyrene insulation panels with mortar adheredto it with a wide range of plastering possibilities of greatversatility and aesthetics, with many decorative possibilities.

The Outdoor Composite Thermal Insulation System,THERMUR, has European Technical Approval

(ETA) awarded by the IETcc, meeting theinsulation and durability requirements ofthe ETAG004 EOTA standards.

Intangible benefitsThis is a quick and easy installation system that allows perfectadaptation of the building to climate, facilitating warming andcooling and preventing possible damp and thermal bridges.It also meets health and safety requirements satisfactorily, re-ducing the risk of discomfort and illnesses in users and the po-tential environmental consequences and maintenance ordeterioration of the building.It is a very versatile system that can be adapted to any existingmedium and does not require the persons to vacate the housefor installation.

SECTOR BUILDING MATERIALS

At its Vicalvaro plant in Madrid, Holcim Moteros has de-veloped a complete range of high conductivity mortarsthat has permitted the correct execution of several geot-hermal installations throughout Spain.

Geothermal energy is a renewable energy that provideseconomic, environmental and architectural benefits for theend-user of the installation, such as reduced greenhousegas emissions, elimination of noise, savings of 50% on theenergy bill, increased useful life of air-conditioning equip-ment, improved aesthetics of the building since there areno visible external elements on facades and roofs; or sav-ing space on rooftops and terraces.

The Holcim products available to the market for imple-menting geothermal installations are:

- HD 2.1 Mortar: Dense, pre-dosed mortar with highthermal conductivity, 2.1 W/mK, and good rheology forits injection.

- HDF 2.0 Mortar: Dense, pre-dosed mortar with high ther-mal conductivity, 2.0 W/mK, and good rheology for its in-jection. Specially designed for installations that requirea small particle size. Maximum particle size: 0.3 mm.

- LD 3.0 Mortar: Pre-dosed slurry with very high thermalconductivity, 3.0 W/mK. Specially designed for installa-tions requiring higher thermal conductivity.

The products are supplied bagged or in bulk. It is alsopossible to develop products tailored to customer needs.

In 2011, a total of 35,300 linear metres of geothermaldrilling was carried out which was sealed with high thermalconductivity mortars manufactured by Holcim. These me-

tres represent an approximate power of 1.8 MWh, result-ing in the corresponding reduction in

overall emissions.

Lessons learnedThe introduction of new energy sources that allow more sustain-able building requires the commitment of all stakeholders, frompublic authorities to the end user, to developers and constructioncompanies. This commitment will allow new sources of renewableenergy, such as geothermal energy, to become a part of the con-struction sector in Spain.

Lessons learnedThe project has made it possible to assess more efficientways of performing operations, taking into account eco-nomic, environmental and social parameters.

“THE STAFF IS MADEAWARE ABOUTTHE USE OF THEBEST AND MOSTEFFICIENTTECHNOLOGIESAVAILABLE”

The Munters equipment dries the humidity from the air using steam to heat the air. After the air has beenheated and the humidity absorbed, the warm air is emitted to the outside of the plant, outside air beingbrought in to repeat the procedure, using energy in the form of steam needed to heat the new air.

To carry out this energy improvement measure, it is necessary to make a modification to the air outlet pipe,installing a static heat exchanger in each of the units and communicating it with the air inlet of each dryer.Since it is a static recovery generator, there is no contact between the incoming and outgoing air and, there-fore, contamination of the new air is avoided, thus fulfilling quality requirements.

In 2012, ESTEVE is carrying out this improvement in eight of the centre’s Munters dryers, those with thehighest operating time, and in 2013 it plans to do so with the rest.

This project has resulted in annual cost savings of 10,390 €, energy savings of 275,939 kWh/year and a re-duction in CO2 emissions of 49,945 kg/year.

SECTOR HOTELS AND TOURISM

NH HOTELS

LED technology has been applied to lighting now for several years. But only recently have lamps becomeavailable that replace the conventional lamps while maintaining 100% of the light levels. Although "low lightlevel" products can be applied to decorative areas, for areas where it is necessary to keep lighting levelshigh it is necessary to use high power products.

Thus, NH Hotels has tested over one hundred different products to replace a halogen lamp in order toidentify the ideal product to be installed in each area. Having chosen the models for each application, thecompany created a catalogue for its hotels indicating which product they should choose for each use.

Thus, needs are identified for each hotel according to the requirements, for example: reception, restaurantand work areas are areas of "high lighting requirement", while the lifts, decorative light sources or lightsources for signs are areas of "low lighting requirement".

Following these premises, in 2012, NH Hoteles has installed over 53,000 LED lamps to replace conventionallamps and expects to have installed 75,000 units by the end of the year. Additionally, LED units are alreadybeing installed for lighting in all replacements.

In later phases, fluorescent tubes will be replaced by theirLED alternative and down-lights with compact fluorescentlamps by LED lamps with similar characteristics. Tests are cur-rently underway with different products.

Besides the usual energy saving, the longer useful life ofthese devices generates savings in the replacement oflamps, which results in a saving on buying new lamps andlower lamp replacement time, which can be devoted to othertasks; less maintenance, as these light sources are not as hotas conventional ones and avoid the appearance of the

blackened rings from the heat of the lamp andtransformer; and lower thermalloads from lighting, which isquite appreciable in areas withlow ceilings or in enclosedspaces, such as lifts.

Specifically, with the implemen-tation of this new system, NHHoteles achieves cost savings of1,980,000 €/ year, energy sav-ings of 18,000,000 kWh/year anda reduction in CO2 emissions of7,560 t.

Intangible benefitsGuests, who know the technology and see it as modern and beingconnected to the respect for the environment, welcome thesemeasures.

Lessons learnedIn the market there is a wide range of LED products of varyingquality. It is necessary to require manufacturers to ensure thatproducts meet minimum guarantees of safety, quality and relia-bility. We have tested products that advertised 50,000 hours oflife and with just 4,000 h had already lost 25% of their light out-put. The same is true for the maintenance of the light colour.Similarly, it is important to bear in mind that there are differenttypes of LED lamps with different sizes and connection sockets.Moreover, you should pay attention to the different colours oflight LED technology permits.LEDs are now no longer just lighting, they are technology. Andthe progress of the new models is as fast as the obsolescenceof the models they replace.

“IMPROVES THECURRENT HEATGENERATION OFTHE FACTORY BY70% TO 90%”

The technology originally installed in the Martorell cogen-eration plant, along with the main components and sys-tems, are now obsolete and with the resulting risk of failure,failing to comply with the future legislation regarding thenew required NOx limits.

Therefore, SEAT has changed and adapted several ele-ments in the aforementioned cogeneration plant with theaim of achieving a higher productivity.

Thus, it has replaced the gas turbine with another of higherefficiency, which enables more efficient operation at partialloads. The burners have also been replaced by others withhigher efficiency and modulation.

Subsequently, new measuring points were installed andthe existing ones upgraded for better control of the opti-mum operating parameters. All this information is con-trolled from a station for the collection of energy data fromthroughout the factory.

Due to this project, the company has improved the cur-rent heat generation of the factory by 70% to 90% and theelectricity generation has risen from 40% to 50% of the con-sumption of the SEAT factory in Martorell.

Specifically, it achieves cost savings of over 2,000,000 €,energy savings of 43,280,000 kWh / year and a reduction inCO2 emissions of 11,700 t/year.

TÉCNICAS REUNIDAS, S.A.

ENERGY SAVING SYSTEM FORTHE OFFICE INSTALLATIONS OF

TÉCNICAS REUNIDAS IN MADRID

In its offices in Madrid, Técnicas Reunidas adopted measures in the three existing supplies that come fromthe general low voltage panel.

The company made an in-depth analysis of the 10th floor and concluded that most of the consumption isdue to lighting and that therefore that is the item where an intervention is necessary. At that time, fluorescentlamps were used which are switched on by electromagnetic ballasts.

Therefore, it is recommended changing to more efficient lighting that allows savings of 40% and requireless maintenance cost. Meanwhile, the implementation of sensors represents a saving of 40% in consump-tion.

The state of existing lighting was also examined and it was observed that, because of inadequate mainte-nance, their efficiency was 70% which results in poor lighting.

Based on the described studies the following recommendations are made:

- Awareness and rational use of electricity- Use of more efficient lighting: replacement of lights with four 36W tubes (260W power) by three 14W

tubes (76W power) – 30% savings- Replacement of 16W electromagnetic ballasts with 1-2W electronic ballasts- Automatic switching off of lights: installation of motion sensors in the 17 floors of the building – 25% savings- Monitoring by floors and scheduled maintenance- Balanced load distribution in all panels- Awareness campaigns

Due to this project, the initially proposedgoal of 25% reduction in energy consump-tion is achieved as well as lowering the eco-nomic cost associated with it.

Lessons learnedBy implementing an energy plan for the Técnicas Reunidasoffices in Madrid, located in the building at Arapiles St. 14,the two fundamental aims for which the plan was imple-mented have been achieved: firstly, to achieve consider-able savings in electricity bills, and secondly, to optimizethe use of natural resources, an aim set forth by the Envi-ronmental Management System implemented in theGroup.Because of the results obtained, during the current finan-cial year two other energy efficiency plans have beenlaunched in order to achieve similar results in two otherbuildings.

CONSUM SOCIEDAD COOP. VALENCIANA

To achieve a reduction in energy consumption, Consum Sociedad Coop. Valenciana has launched a Savingsand Energy Efficiency Plan, for which the energy consumption of each element of its facilities is analysed,establishing their structure according to the end uses, and setting consumption levels according to theircategory and location.

This Plan, which aims to reduce the impact the company has on the environment, is based on three mainlines of action, namely:

1. Manual of Good Habits on Efficient Use of Equipment and Facilities: education and awareness of em-ployees on the proper use of equipment and facilities is the cornerstone of the launch of the Plan.

2. Systems for Controlling and Monitoring Energy Consumption: this system allows measuring the con-sumption of each point of supply and, therefore, optimizing its operation by automating any repetitiveprocesses and implementing different savings strategies according to the season and use thereof, es-tablishing improvement actions.

3. Use of more efficient technologies: the organization is equipped with machinery and facilities of a hightechnological level thanks to the different measures that are still applied today.

This system allows us to know both the information necessary to implement the most effective measuresand real-time consumption to avoid deviations from expected consumption.

Specifically, the cost savings achievedthrough the implementation of the Planare 9,400,000 €, the energy savings are72,307,692 kWh and the reduction in emis-sions is 16,125 t of CO2.

Intangible benefitsDecrease in the daily tasks of staff due to automation ofprocesses and increased comfort at the point of sale.

Lessons learnedThe main motivations for joining this challenge havebeen the cost reduction, the adoption of improvementprocesses, the organization's commitment to the envi-ronment and the viability of these actions. In summary, the project described has supported a com-prehensive control, avoiding unnecessary losses that donot produce any added value.

SECTOR PRODUCTION ANDURBAN DISTRIBUTION OFHEAT AND COLD

DISTRICLIMA, S.A.

Since 2004, the company, Districlima, S.A., with the participation of Cofely Spain SAU (Grupo GDF-Suez),Aguas de Barcelona, TERSA, ICAEN and IDAE, has operated the urban heat and cold distribution networkin Barcelona, in the Forum Area and 22@ Technological District.

Thanks to its shareholders, administrations and clients, Districlima is currently the largest network in thecountry in terms of size, diversity of clients and implementation in the urban area of a large city.

Energy production takes place mainly in the Fòrum Plant, near the exhibition centre where the Forum ofCultures 2004 was held, which also gave rise to this project. Substantially all heat supplied as driven waterat 90°C and a good part of the cold supplied as driven water at 5°C is produced from the steam from theneighbouring TERSA waste incineration plant. There is a second plant to meet peak demands and pumpingrequirements, which has been recently opened, namely in April 2012 and which is worth mentioning, due toits sophisticated ice accumulation system.

The Fòrum plant features two absorption units and four electric coolers (29 MWf in total), all condensed byseawater, and four steam - water exchangers (20 MWc) and a 20 MW back-up gas boiler.

The distribution network runs across the Besòs area and the 22 @ technology district, supplying over 70buildings of all kinds, from business parks, universities, social housing, health centres and hotels, to shoppingcentres, restaurants or office buildings.

Thanks to this system, energysavings of 61,960 MWh PCIand a reduction in CO2 emis-sions of 10,900 t wereachieved in 2011.

Intangible benefitsThe connected buildings benefit from increased energy efficiency rat-ings, gain useful spaces and make other architectural solutions possible,eliminate maintenance costs and future replacement of equipment;eliminate noise and vibration and the presence of combustible gasesor hazardous elements; facilitate power increases with hardly any addi-tional investment; and have supply guaranteed thanks to the large num-ber of plants and equipment available. Another aspect to consider isthat they always get the most economical and efficient energy, sincethey automatically benefit from the technological improvements andupdates carried out at the plants.Cities and the society, meanwhile, benefit from a minor dependenceon foreign energy, the overall reduction in electricity consumption andthe minimization of electricity and gas infrastructure; health risks areavoided; greenhouse gas emissions are reduced; smart cities are madeup, architecturally avant-garde, with sustainable buildings that are tech-nologically "updatable" in terms of heat production; it is possible to in-tegrate various energy sources, also on a local level, which wouldotherwise be wasted, among others.

Lessons learnedThe development of this type of projects in urban areas is closely linkedto housing development and urban transformation and should be partof the planning from the beginning. Such long-term development rarelyrespects the original estimates so it is necessary to have a significantinvestment capacity, concessional-type entrepreneurial attitude and theinvolvement of several agents.

PROVISION OF ENERGY SERVICESFOR HEAT SUPPLY AND SUBSEQUENT

USE IN THE HOT WATER CIRCUIT OFTHE PROCESS, THROUGH THE

CONSTRUCTION AND OPERATIONOF A COGENERATION PLANT

Industrias Cárnicas Villar1 consumes a large amount of hot water in its production process. The hot water isusually produced by a boiler using natural gas as fuel.

The installation of a cogeneration plant would improve the energy efficiency of the process. Cogeneration isa highly efficient technology and from the primary energy provides both heat for the hot water circuit of the in-dustrial process as well as electricity, which is transferred to the network, which enables the recovery of over75% of the primary energy used.

Endesa comprises the provision of energy services in its energy efficiency strategy and reduced consumptionfor its clients, which includes the replacement of equipment and facilities by others of greater efficiency, thegradual reduction of energy consumption per production unit and the continuous improvement in facilitieswithout affecting its normal activities nor reducing the quality and safety standards of each facility.

Specifically, in the comprehensive cogeneration service provided, Endesa assumes the financing of the project,procedures, execution of the work and its subsequent operation and maintenance.Having conducted the nec-essary audit and feasibility studies, it proposes the provision of a comprehensive cogeneration service. In thisway, through an energy service contract, Endesa supplies the heat required for the industrial activity, reservingand minimizing the use of the boiler.

Meanwhile, the electricity generated by the cogeneration is fed into the medium-voltage network of the dis-tribution company. The installation consists of a cogeneration plant with a 500 kWe alternative engine. The heatfrom the hot gases discharged from the engine and the heat from the engine jacket are recovered to producehot water at about 90°C, about 530 kWt, which Endesa supplies to Industrias Cárnicas Villar at a more compet-itive price than if it were produced with a conventional system.

The simple recovery of investment for the Energy Services Company is achieved in approximately 4.5 years;meanwhile, Cárnicas Villar achieves a saving of 15% on its energy bill right from the start.

Furthermore, the replacement of conventional systems by cogeneration for heat production results in a savingof 4,257 MWh/year of primary energy.

The project started in January 2010 andimplementation of the installation wascompleted in May 2011.

“THE CLIENTOBTAINS A SAVINGOF 15% ON ITSENERGY BILL RIGHTFROM THE START”

Intangible benefitsThe outsourcing of the risks and responsibilities related tothe construction and operation of the plant, increased com-petitiveness due to the reduction of energy costs, espe-cially in sectors with intensive energy consumption, andcontribution to CO2 emission reduction, energy savingsand consequent reduction of energy dependence.

Lessons learnedThe food sector has great potential for the implementationof cogeneration plants; cogeneration plants should be de-signed to meet the basic demand for thermal energy, anessential criterion for a high level of overall efficiency; co-generation is a highly efficient system which allows an im-proved competitiveness of companies with significantthermal energy consumption; installation is easily replicableand adaptable to any heat consumer.

Intangible benefitsIt has been possible to sensitize employees on environmen-tal issues, minimize maintenance of equipment (compres-sors), reduce the time of equipment out of service andincrease production capacity.

Lessons learned1. Through leakage control, equipment maintenance defi-

ciencies are corrected.2. Without excessive work by the company itself some im-

provements can be detected without the need for invest-ment, related to compressed air leakage management(immediate results).

3. Promoting communication channels that facilitate themanagement of expert knowledge.

4. Informing company staff of the high production cost ofcompressed air.

5. The fewer leaks, the less the unnecessary work of com-pressors, discharge time, energy consumption, number ofrepairs required by the equipment and number of shut-downs.


Air is free until it is compressed. Once compressed, it becomes energy and this has a cost. Therefore, whenthere are leaks in compressed air pipes we are talking about economic losses.

Compressed air systems are present in most industries, as they improve productivity by automating andaccelerating production. Compressed air represents approximately 10% of all electricity used at industriallevel and it is present in almost all industrial facilities.

Therefore, the main aim of the project which is carried out by Ferro Spain is the location of possible leaksin the compressed air distribution network. Experts say that the acceptable level of leakage would be be-tween 5% and 10%, since it is sometimes as high as 30%.

The project is divided into two phases. The first involves the analysis and identification of areas for improve-ment that require a small investment. To do this, it is necessary to locate the air tubes or branch lines whichare not in use currently, as these tend to be a potential source of leakage. The second phase involves theimplementation of an effective system to detect leaks and repair them immediately.

With regard to cost management, this project is segmented into two parts: the cost of detecting com-pressed air leaks with specialized equipment and the cost of repairing them. The return on investment timeis always less than one year.

With this practice, the company achieves energy savings of 700,000 kWh, cost savings of 70,000 € and anemission reduction of 250 t of CO2.

Lessons learnedSimply by using what is allowed to es-cape through a chimney it is possibleto reduce energy consumption andhence emissions to the atmosphere.The simplest things can often be themost profitable.

The opportunity is identified to tap thelatent heat of the vapours from the boil-ing of must which is lost through thechimneys of the boilers, by condensingthem to preheat the must and to gen-erate water at 850C. This makes it pos-sible to reduce energy consumptionand thus emissions to the atmosphere.

Specifically, Mahou-San Miguel achievescost savings of over 600,000 € a year,energy savings of 22,000,000 kWh PCSa year, and a reduction in CO2 emis-sions of 4,433 t a year.

It also reduces the peak heat demandof the factory and, consequently, in-creases the security of supply sincethere is a greater installed capacity inreserve to cover boiler breakdowns ormaintenance. The emission of unpleas-ant odours propagated by brewingvapours is also reduced by 60%.

In November 2011, the international version in energy management systems, EN ISO 50001:2011, is adoptedas a Spanish standard, replacing the current UNE-EN 16001:2010.

The new approach of the UNE-EN ISO 50001:2011 standard seeks alignment with the regulatory provisionsthat have been applied at international level in recent years, therefore, also in the framework of the EU, to fightagainst climate change, one of whose main causes lies in the emission of greenhouse gases caused directlypower generation and consumption activities.

Therefore, Red Eléctrica de España, S.A.U., which since October 2011 has been certified by AENOR in the En-ergy Management System-SGEn- under the UNE-EN 16001 GE-021/2011 standard, sets itself the goal of beingcertified according to the new standard, for which it is implementing the "Plan of Energy Management Im-provement Measures at its Headquarters for the period 2012 - 2019".

This savings programme includes, among other measures:

- Lighting: implementation of a lighting control system in areas for administrative use; installation of non-adjustable electronic ballasts in areas for administrative use; replacement of fluorescent lamps in basementcar parks; reduced voltage in outdoor lighting; presence sensors in toilets; presence sensors in basement liftcore; reduced lighting in computer rooms by means of switches; light sensors in offices; reduced lightinghours in lifts.

- HVAC: replacement of autonomous equipment with more efficient equipment.- Water: implementation of green Cold Opening cartridges in mono-control taps.- ACS: installation of a solar thermal collection system.- Pumps: variable speed drives on booster pumps.- Motors: replacement of standard motors by others with improved efficiency; installation of variable speed

drives in lifts.- Office Automation: installation of smart power strips.

Specifically, this project is expected to result in cost savings of 30,882 € a year, energy savings of 354,139 kWha year, and a CO2 emission reduction of 124 t a year.

Intangible benefitsIncreased knowledge of the consumption profile of theheadquarters and identification of potential savings andproposed improvement actions for the potential identi-fied, e.g. identification of savings in stand-by and pro-posal of smart power strips.

Lessons learnedThere are improvements in energy consumption as aconsequence of the introduction of more efficientequipment without impairing user comfort. In addition,it contributes to the awareness of employees about theimportance of energy efficiency in the workplace.

IMPLEMENTATION OF ANENERGY MANAGEMENT SYSTEM

Lessons learnedDetailed knowledge of the influence ofeach facility on energy consumption al-lows the definition of realistic consump-tion targets.Meanwhile, the quantification of the ac-tual savings achieved in the implemen-tation of measures is a motivating factorfor the definition of new measures.

Volkswagen has installed hardware consisting of electric and gas meters in all areas of its plant in Landabenthat it wishes to control, PLC and servers. With this system, each user can know the real influence of eachelement and operating times in the energy consumption of his facility or workshop. This information, foreach of the facilities, is sent automatically to a single information system for further analysis.

This is used to select the periods and facilities where a greater potential for reducing consumption is iden-tified and define the necessary technical and organizational measures. For these cases, stop and start timesor operating conditions of these facilities cloud be shaped.

This work of analysis and modification of operating conditions is performed weekly to see how it affectsconsumption, since the system permits verification of the actual reduction in consumption following imple-mentation.

Specifically, this project has provided Volkswagen with costs savings of over 168,000 €, energy savings of5,139,000 kWh /year, and a reduction in CO2 emissions of 1241.08 t /year.
